We are looking for the possible blood types of a baby.

Parental information:

  • Mother type A negative -- can be AA or AO and Rh (--)
  • Genes: A, O, (-)
  • Father type A -- can be AA or AO and Rh (--)
  • Genes: A, O, (-)
Baby recieves one gene from each parent:
  • Baby is type AA Rh (--) = Type A neg
  • Baby is type AO Rh (--) = Type A neg
  • Baby is type OO Rh (--) = Type O neg
If both parents are A neg, then they would have an Type A neg or O neg child.

The child cannot B because the parents do not carry a B gene, and cannot be Rh positive since neither parent carries the Rh (+) gene.

We are looking for the possible blood types of a baby.

Parental information:

  • Mother type A neg --can have AA or AO with Rh (--)
  • Contributes genes A, O, (-)
  • Father type O pos --can only have OO with Rh (++) or (+-)
  • Contributes genes O, (+), (-)
Baby receives one gene from each parent:

Note: in each case the baby can have either Rh pos or neg blood.

  • Baby is type AO = Type A pos/neg
  • Baby is type OO = Type O pos/neg
With A neg and O pos parents, the baby's blood type will either be A or B and Rh pos or neg.

Yes, blood types are inherited through genetics of your parents and ancestors.

Parents of blood type O can only have children with blood type O. Because type O is recessive, you know that the parents are homozygous O.


What are the possible blood type outcomes of offspring with a mother with type A plus blood and father with B plus blood type?

This would depend on what the genotype is of the parents. They could have children with type A, B, AB, or O type blood. This is possible if they are both heterozygous if they are homozygous for their respective blood types they could only have AB children. Also the statistics for the blood types would change if one parent was homozygous and one parent were heterozygous.


Are all children of same parents the same blood type?

of course they can, it doesnt mean that if you dont have the same blood type as your siblings, your adopted or something. if your parent's blood types differ from each other there is a huge tendency that the sibling's blood types are different from each other. for exaple your father is a heterozygous A while your mother is a heterozygous B.. their children's blood types can be AB, and an O can also be one of the possiblities.. if its too complicated to understand then you can just learn it from your genetic lessons in biology..


If male has type a and female has type ab what are the possible blood types of their offspring?

The blood type will be the same as one of the parents or a combination, so A or AB. If the parents both have the same Rh factor (+ or -) the baby will have that factor, else it could also be either. The risky situation at birth is where the baby's Rh factor is not the same as the mother's.

Does your ethnicity affect your blood type?

You get your blood type (phenotype) from your parents, each of whom carry their parents blood types (genotype) in their blood. Your ethnicity plays a minor factor because some races tend toward different blood types, but any member of any race can end up with any blood type. Four children of the same parents could all have the different types of blood.
